How to use SearchLink?

I am trying to use SearchLink to have the highlighted text be searched in Google and the first result copied to the clipboard automatically by pressing a keyboard shortcut.

I installed SearchLink as a service, set up a keyboard shortcut, typed some text in Sublime Text, added !!^ at the end, highlighted and pressed the shortcut. Nothing happens i.e., no URL got copied to the clipboard. Also tested in the browser (Microsoft Edge) and the same.

Any idea?
